Loose-LEAF 'BINDER specification of um Patent Patented oct. 25, 1910.

Application and February ze, 1910. sex-m No. 548,095.

To all when; 'itmoy concern Be `it known that.' we, HENRY G. FoRNoFF and HENRY C. Krauss, ctizensof the United 'States of'America, residing in the city of St.'-

Louis and 'State of Missouri, have invented certain A new and useful Improvements in ALoose-Leif Binders of which the followin binder of this Vdescription .means whereby the posts that receive thev loose leaves are adjustably mounted :in order that they ma be shifted'to properly s ace them accor erforations in the leaves that-are to be us in theV binder 'and which means also rovides for the removal or insertion of eaf receiving posts to supply the' binder with the requisite number o posts according to the number of perforations in' the loose leaves.

.Oui-.invention further relates to a novel clamping means for e agement with the binder'post s to holdt e top cover positively ositioned'relative to the lower cover of the. inderafter-the loose leaves have been applied to the binder posts.

lFi ure I is a view partly in plan and art y in section of the rear portion of our inder.`.-Fig. II is a longitudinal section taken on line II-II, Fig. I. Fi 'III is 'a cross section taken on line III- II, Fig.

I. Fig. IV is 'an' enlarged cross section taken ective View ofone of the posts of the binder and a -fragment of the post holding rod 'shown in' theposition the rod occupies whenthe binder posts are in stationarypo-v sitions. Fig. :VI is an enlarged perspective view of one 'end of the post clamping device A that are per orate'd neartheir'rear edges,

ns= us1 1al,=the' j perforations providing for the leaves being"appli`ed to posts 'ofthe binder that will be hereinafter described.

5 designates a tubular housing located in the poclretmember'2 ofthebottom cover 1 and 'is preferably ofoval shape in cross section and inthe upper wall 'of which is a slot 6 that regi-sters with a slot 2 in the top of the pocket member, these slots being provided to posts vlongitudinally of the pocket member 2 and the housin 5 therein.

7 desi ates tige binder posts, which are provide with heads 8 movable`within the housing 5, while the stems of said posts extend vertically through the slots 6 and 2. The head of each Apost 7 contains a noncircular aperture 9, preferably of oval shape, and in each head, at the aperture therein, are serra-tions 10 that are located in 4the wider walls of the aperture, while the remainder ofv the aperture is of smooth bore..

1l'designatesa non-circular post holding rod that extends throu h the heads of the posts of the binder, an the edges of which are provided with serrations 12, While the sides of 'the rod are smooth as seen at 13. It will be readily appreciated that when the non-circular post holding rod 11 is in such position in the heads of the post 7 that its surfaces of the apertures in the posts may be moved at will longitu the rod 11', whereas,vvhensaid rod is turned posts to bring its serrations into engagement with the serrations 10 in the post heads, said posts are held from movement upon the rod.

lermit. `movement ofthe binder latand 15, (see Fig. II), are'bearing blocks I mounted in 'the housing 5 near its ends in which the post holding rod 11 is rotatably fitted The bearing block 14 receives the post holding rod near one of its ends and ata point at which theserrated and smooth surfaces are present, while the bearing block 15 contains acircular bore that receives a. round stem 11* at thev end of the rod farthest removed from that supported in the bea-ringl bloc/R14. The aperture 14 in the bearing."

block 14 through which the post holdingrod' extends isnon-circular in shape and partially threaded and partially smooth,in cor respondence to the apertures in the hea ds of the posts 7 thereb providing for the post holding rod being lie d fromendwise movement m vsaid block when the serrations of.-

the rod arein engagement with the'serrations in the block', and also roviding' for. said rod beingmoved longitudinally through the block when the serrations in 'said rod areout of enga ment with the serrations in Asaid block. t one end of the post holding rod is a key receiving head 11" to which a key may be applied for the purpose ofturning the rod, and the rod is provided with 'a' rod in one direction to a de ree greater than that whichwill provide or the post heads being locked to the rod is prevented.

16 is a set screw mounted in the bearing block l14 and extending transversely therein4 relative to the ost holdin rod. This set screw 'is adapte to Iiinpir e against one of the sides -of the post holcing rod, as seen in Fig. III, when said'rod is in post holding position, thereb preventing accidental rotation ofthe rody; and the screw is provided with :whey receivingphead 17 that is accessi ble all the rear edge of the pocket member 2 through apertures 2 and 5 respectively located in the pocket member 2 and housing 5.

in mointing thel binder posts/of our binder, the post holding'rod 11 is introduced into the binder by passing it first through opening 2* of the Fig. Il), then throng the bearing block 14 so that its serrat-ions are opposed te the unserrated walls of the bearin posts are put in place so that t eir heads are present within the-housing 5,and the post holdin-g rod is slipped through them while the serrations of the rods and the serratioiis in the apertures of the of engagement with eaci other, the introduction of the -rod being continued until its stem 11 has been iassed through the beating block 15. -During the' introduction of @the ost holding rod, the Set screw 16 is inail-e- 'racted position tc permit the passage of the rod through the bearing block 14 and, therefore, after .the ost holding rodhas been entirely inserted), it may be readily turned until its sei-rations are brou 'lit into engagement with the sei-rations in tie beati'- ing block 14 and in the heads of-the post-57 to prevept endwise movement. of the rod and also to prcverit shiftin of the post s upon the rod so that they wil? remain in positions to whichtheyare adjusted. After the post holding rod has been turned, as stated, to

A lock it in place, it is held from rotation by` inward movcment'of the set screw 16 actu'- .atcd by a suitable key and which upon its inward movement impinges. against aside of the rod,- as seen in Fig. III. It should be noted that the posts may be quickly adjustcd in any desired degree by freeing the rod of the holdingollice exerted by the set screw 16g-'and then turning the post holding rod to place its serrations out of engagement `with the seri-ations in the heads of the posts,

v' A thereby permitting movement of the posts Aupon the rod', after which the rod is reta-ned to its former position and held from moveocket 'member 2, (seeblock. The

ost heads are free 4@through transverse slots 26 Ain the clam ment as before.` Itis also to be noted that the post holding rod may be partially withturning it into the position it occupied w en it was inserted for' thepurpose of permitting se aration of a post,'or posts, from the rod an their removal` from. the part of the Amitthe. mounting of a` 'greater number of posts than previously in placein thel binder. We will next proceed with the description ofthe clamping means by which the upper cover 'is secured to the binder posts. In the inner and outer walls of the pocket 'corresponding in dimensio'ns'to the slot4 2 -and the slut 6, respectively, in the pocket member 2 of the bottom cover and the housing 5 within said cover.

18 is a housing within the pocket member 4 and which preferably corresponds iii shape to the housing 5 in the pocket member 2 of the bottom cover. This housing 18 lis provided with slots 19 in registration with 'thc slots 4 in the pocket member 4 and through which, as also through the slots 4', 'the' binder posts 7 are' adaptedto pass when the 'top cover is placed upon thesheets of. paper laid upon the bottom cover.

20` designates clamping bars loosely mounted in the housfag 18 at opposite sides of engagement with the binder posts when they are present in the pocket members 4. Each clamping bai-'is provided with runners drawn from the binder 'at anytime u ou binder by which they are carried. or to per member 4 of the upper cover are /Slots 4".

of the slots-19 therein and which are adaptedtobe moved into engagement with and out 21 that ride m engagement with the bottom and top faces at the interior of the housing 18 to reduce the frictional engageinentb Vtween said bars andhousiii Each clamping bar is also`provided with slots 22 extending diagonally therein, and at'its outer edge with inclined faces. 23 that extend' diagonally' with the bars parallel with said slots'. The diagonal slots 22 receive guide pins- 2l rigidly mounted in the bottom and top.of the housing 18 and the inclined faces 23. which are'located throughout the length of the clamping bars between the diagonal slots 22, receive guide pins 25, also rigidly. mounted in the bottom and top ofthe housing 181 so that ends of' the c amping ars 20 ma be confined between wings thereof. This `elamping bars by'pivot pins 28 mounted in lthe shifter head and extending loosely. mg 'bars, (see Eins. I and VI). The .shifter head is proiiided with a. T-slot 29 located rovided with a key -receiving head 32 an'd is rotatably mounted in a bearing block 33,

27 isa shifter head, referabl of Ushape, l

shifter head Ais loosely connected to the midway of its-length,4 and which receives'` the head 30.l of a shifter screw 31 that is I other position.

'uiscrewgthreaded internally td receive the `.sage o f the binder posts.

when the top cover is put 1n place in the shank 4of 4the screw.l Assuming that the clampingr bars 20 are. lrod sufficiently separated to permit ofthe. as

binder, the posts will. pass between these bars ready to be engaged by the bars when they are moved toward each other. Then,

to effect a clampin 'action of the post upon the bars, itis, only necessary to turn the shift screw 31 in the -proper direction, whereby the shifter head 27 is moved inwardly andncts to impart endwise movement to the clamping bars. These barsare, during their endwisefmovement caused to move laterally toward the. binder .posts and`become engragpdtherewith, due o the riding of the clampinar bars against t elguide pins Q4 that extend through the diagonal slotsl22 and also due to 'the riding 'of the inclined faces .23 of the clamping` bars against the guide pins 23. A4 movement of the shift screw 31` direction provides for the clamping bars being moved backwardly re1- ative to their first movement, with the result ofdisengaging the clamping bars from the ,binder'posts when it is desired to remove the top cover. wie claim 1.
